This paper presents a new approach for providing contextual information in real-world environments. Our approach is consciously designed to be low-threshold; by using mirrors as augmented reality surfaces, no devices such as AR glasses or smartphones have to be worn or held by the user. It enables technical and non-technical objects in the environment to be visually highlighted and thus subtly draw the attention of people passing by. The presented technology enables the provision of information that can be viewed in more detail by the user if required by slowing down their movement. Users can decide whether this is relevant to them or not. A prototype system was implemented and evaluated through a user study. The results show a high level of acceptance and intuitive usability of the system, with participants being able to reliably perceive and process the information displayed. The technology thus offers promising potential for the unobtrusive and context-sensitive provision of information in various application areas. The paper discusses limitations of the system and outlines future research directions to further optimize the technology and extend its applicability.
This paper presents a novel approach to notify users about tasks in their immediate environment. Our approach is consciously designed to be low-threshold, by using augmented mirror displays, no devices such as AR glasses or smartphones have to be worn or hold by the user. The mirror display allows people passing by to get awareness of which technical and non-technical objects that need attention in an unobtrusive way. These are conveyed visually in a uniform manner and can be easily observed by passing users. If the user decides to interact by slowing down or pausing, the display adapts to more detailed information about the augmented objects. Users can decide whether this is relevant to them or not. We present a novel interaction concept, several use cases, an implementation of our approach in a laboratory scenario and conduct a user study to evaluate the feasibility and effectiveness of our interaction concept. The results reveal a good performance of our system and based on this, open up new questions perspectives for future enhancements.
The new seminar "Digital Twins for Virtual Commissioning of Production Machines" follows a technical approach that uses virtualization and offers the possibility to pursue an uncommon teaching method called problem-based learning (PBL). The seminar is divided into two parts, with fundamental theoretical knowledge in automation technology and systems modeling provided first. In the second part, the students use the dedicated software environment to edit projects on their own, and at this point the PBL approach is used. This method enables students to self-organize their learning process and take an active part in the seminar. The idea for the seminar and virtual teaching lab evolved from the industrial use case of testing software for programmable logic controllers (PLCs) without the real machine, using virtual commissioning (VC). The primary effort of VC lies in the manual creation of a digital representation of each mechatronic component providing the same behavior seen from PLC perspective. Students are taught to do this, create the so-called digital twin (DT).
In der Debatte um die Nachhaltigkeitsberichterstattung geht es immer wieder auch um die Frage, wie künftig Standards im Reporting effizienter gestaltet und Synergien besser genutzt werden können. Dieser Beitrag vergleicht das Regelwerk der CSRD bzw. der ESRS mit dem des EMAS und stellt praxisnah dar, wie beide Standards in der Umsetzung sinnvoll verknüpft werden könnten, um letztlich bürokratischen Aufwand bei der Berichterstattung zu verringern und redundante Prüfprozesse zu vermeiden.
Purpose
The German Supply Chain Due Diligence Act (GSCDDA), as a comprehensive regulation for due diligence in supply chains, will exert profound pressure on companies’ sustainable supply chain management (SSCM). This study aims to examine the affected stakeholders’ polarizing expectations stemming from the GSCDDA, the resulting impacts on SSCM and how these findings compare with theoretical SSCM developments.
Design/methodology/approach
From 5,490 GSCDDA posts on X (formerly “Twitter”), the authors extracted 556 qualitative posts illustrating the GSCDDA discourse and analyzed them from a stakeholder perspective. The posts were classified according to the dimensions of stakeholder groups and expectations (i.e. challenges and opportunities). The authors then synthesized the posts across these dimensions and compared the identified expectations with the SSCM literature.
Findings
Seven stakeholder groups were identified, along with nine challenges (e.g. legal flaws) and four opportunities (e.g. increased transparency). The synthesis of both components revealed highly discussed and conflicting expectations. The theoretical SSCM developments partly differ from the discourse, indicating discernible gaps between theory and practice
Practical implications
Identifying key stakeholder groups supports building synergies between GSCDDA implementers and stakeholders to tackle their challenges and reinforce opportunities.
Originality/value
Due to the growing prevalence of supply chain due diligence regulations, it is essential to consider the legal implications for SSCM. This study explores the link between due diligence concepts and SSCM, and to the best of the authors’ knowledge, this is the first study to analyze how legal pressure shapes stakeholders’ expectations on companies’ SSCM.
Mit der Einführung der Corporate Sustainability Reporting Directive werden Prüfpflichten zu den im Lagebericht publizierten Nachhaltigkeitsinformationen eingeführt. Der vorliegende Beitrag widmet sich den Fragen, was geprüft wird, wer prüft und wie geprüft wird. Abschließend wird kurz die nationale Umsetzung der Prüfpflichten ins deutsche Recht angesprochen.
Regulierung als Chance
(2023)
Unternehmerische Risiken können nicht mehr losgelöst von Nachhaltigkeitsrisiken in einer „flüchtigen Moderne“ betrachtet werden. Entsprechend fordern die jüngsten Gesetzgebungsverfahren der EU‑Kommission ein intensives Auseinandersetzen mit Nachhaltigkeitsrisiken. Dies macht neue Formen und transparente Ansätze des unternehmerischen Risikomanagements notwendig.
Unsere Welt wird komplexer, schneller und unübersichtlicher. Bisher geltende Wahrheiten lösen sich auf. Lebensstile, Wirtschaftsstrukturen und Konsummuster überschreiten planetare Grenzen, die eine Transformation in Richtung Nachhaltigkeit dringend nötig machen, um unsere Handlungsspielräume nicht völlig zu verspielen. Aktuelle und drohende Krisen auf der einen und Handlungsräume und -möglichkeiten auf der anderen Seite erfordern heute innovative Lösungen, Strukturen, Partnerschaften und letztlich Entscheidungen von uns, deren Konsequenzen und Wirkungen wir in langer Perspektive kaum abschätzen können. Das gilt für die Politik-und im gleichen Maße auch für die Wirtschaft mit ihren am (globalen) Markt agierenden Unternehmen. Es erscheint zunächst als eine Binsenweisheit: Entscheidungen mussten schon immer unter Unsicherheit getroffen werden. Aber bei näherer Betrachtung wird deutlich, dass es durch strukturell steigende Vielschichtigkeiten, Vernetzung und Widersprüchlichkeiten immer schwieriger wird, zu verstehen, zu vermitteln und zu beurteilen, was vermeintlich richtig oder falsch ist. Alte Formen der Wissensgenerierung, aber auch die Aufbereitung von Wissen halten mit der steigenden Komplexität kaum noch Schritt. Neue Formen des Wissens, das sogenannte Transformationswissen, werden künftig gebraucht. Hierbei können immersive Technologien wichtige Vorteile bieten.
